Summary

Adds a new rector rule FormExecuteToProcessRector that automatically renames deprecated Form::_execute() methods to process() for CakePHP 5.3+.

• Form::_execute() is deprecated in CakePHP 5.x
• The new process() method accepts the same parameters and has the same return type
• The rule includes a safety check to skip renaming if process() already exists to avoid conflicts

Changes

• New Rector Rule: src/Rector/Rector/ClassMethod/FormExecuteToProcessRector.php

  • Handles renaming _execute() to process() in Form classes
  • Preserves method signature (parameters and return type)
  • Skips transformation if process() already exists

• Tests: Complete test coverage with:

  • Basic transformation test
  • Skip logic test (when process() already exists)
  • All tests passing ✓

• Configuration: Added to config/rector/sets/cakephp53.php for CakePHP 5.3 migration

Test plan

• Unit tests pass (2 tests, 3 assertions)
• Code style check (phpcs) passes
• PHPStan analysis passes
• Integration test verified with sample Form class
• Skip logic verified when process() method exists
